Summary Introduction

To apply:

Heart-lung transplants are performed in some cases in which both organs have been damaged by cigarette smoking. Given a scarcity of organ donors, determine the criteria that would be used by an individual in selecting a recipient for such a transplant.

Introduction:

Smoking is inhalation and exhalation of burning cigarettes fumes containing tobacco. The smoke of cigarette tends to have a negative impact on the organs that are in direct contact of smoke as well as on the organs that are not in direct contact (as individuals inhale smoke present in the surrounding exhaled by smokers cigarette).

Expert Solution & Answer

Explanation of Solution

Considering the problems involved in finding donor lungs and hearts (vital organs), they can be obtained from cadavers, except in the rare scenario of single lung donation. Choices must be made to decide who gets these organs. Smoking, being a serious addiction has been part of a massive public push for better part of 30 years.

Factors involved in making the decision to provide an available lung-heart pair to a recipient should include:

(i) Age of patient.

(ii) Commitment to quit smoking through either drug treatment or health program.

If an individual cannot commit to either of the programs then it could be simply waste of organ as the new organs will again be destroyed in a similar fashion.

Conclusion

The criteria that would be used by an individual in selecting a recipient for such a transplant include age and commitment to quit smoking by the patient.

. Consider a base substitution mutation that occurred in a DNA sequence that resulted in a change in the encoded protein from the amino acid glutamic acid to aspartic acid. Normally the glutamic acid amino acid is located on the outside of the soluble protein but not near an active site. O-H¨ A. What type of mutation occurred? O-H B. What 2 types of chemical bonds are found in the R-groups of each amino acid? The R groups are shaded. CH2 CH2 CH2 H2N-C-COOH H2N-C-COOH 1 H Glutamic acid H Aspartic acid C. What 2 types of bonds could each R-group of each of these amino acids form with other molecules? D. Consider the chemical properties of the two amino acids and the location of the amino acid in the protein. Explain what effect this mutation will have on this protein's function and why.
engineered constructs that consist of hollow fibers are acting as synthetic capillaries, around which cells have been loaded. The cellular space around a single fiber can be modeled as if it were a Krogh tissue cylinder. Each fiber has an outside “capillary” radius of 100 µm and the “tissue” radius can be taken as 200 µm. The following values apply to the device:R0 = 20 µM/secaO2 = 1.35 µM/mmHgDO2,T = 1.67 x 10-5 cm2/secPO2,m = 4 x 10-3 cm/secInstead of blood inside the fibers, the oxygen transport and tissue consumption are being investigated by usingan aqueous solution saturated with pure oxygen. As a result, there is no mass transfer resistance in the synthetic“capillary”, only that due to the membrane itself. Rather than accounting for pO2 variations along the length ofthe fiber, use an average value in the “capillary” of 130 mmHg.Is the tissue fully oxygenated?
Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
